Bitter metallic taste after eating pine nuts?

I have this bitter, metallic taste in my mouth every time I eat. It started this morning. I googled it and found a number of blogs with posts from people saying they experienced this bitter metallic taste in their mouth 2 days after eating pine nuts. I thought back…and yes, I ate pine nuts two days ago. Has this ever happened to anyone else on Fluther? If so, how long did it last? It is really unpleasant and I hope it doesn’t last too long. I’ve eaten pine nuts many times in the past and have never had this problem…but some postings say this is specifically happening with pine nuts from China.
